Symptom

Server communication problems after the reconfiguration of the NWDI admin user/password.
Other terms

NWDI, admin user, user update, password update, user/password update, communication error, landscape user, domain user
Reason and Prerequisites

The new user/password configuration is not updated in all NWDI landscape servers. The automatic update is not implemented.
The use case / Precondition:
In the NWDI CMS Landscape Domain Data UI the admin user and password are defined. In addition at least one NWDI track is already configured.
The NWDI administrator has to change the NWDI admin user/password.

Solution

In order to update the new user/password configuration for all NWDI Servers manual steps are required.
The required steps:

1. In case you only want to change the password it is recommended to stop CBS on all your CBS servers before the change. This will prevent CBS doing background builds with the old credentials.a) Stop the CBS in Visual Admin -> Server -> Services -> Component Build Service2. Change the NWDI admin user/password configuration in UME or corresponding user store (e.g. ABAP, LDAP, …)3. Change the NWDI admin user/password configuration in the NWDI CMS Landscape Domain Data UI (CMS User, CMS Password).4. In NWDI versions older than 7.00 SP 13 you need to update User/Password Configuration in the configured CBS Buildspaces if necessary with the following steps:a) in CMS UI -> Landscape Configurator, for each trackmake a change in the XML Content of one software component of the track. Add the line “” in the XML Content as the first line. Use “View/Edit XML” button on the Developed Software Component table.if needed, change user / password for runtime systems of the current track, toosave the track (do not use “save and restore” in the popup)b) IF AND ONLY IF there is CBS Communication Exception shown at the bottom of the page, you should follow the steps listed below:in Visual Admin -> Server -> Services -> Component Build Service, set IdleStart as true, then restart CBS.restart the J2EE Enginemake sure that the NWDI admin user is unlocked after engine restart with help of UME. In case the user is locked, unlock it.in CMS UI -> Landscape Configurator, for each track
I) make a change in the XML Content of one software component of track.add the line”” in the XML content as the first line. Use “View/Edit XML” button on the Developed Software Component table.
II) if needed, change user / password for runtime systems of the current track, too
III) save the track (do not use “save and restore” in the popup)in Visual Admin -> Server -> Services -> Component Build Service, set IdleStart as false, then restart CBS.c) After having saved all tracks with Buildspaces, navigate to Transport Studio and restore system state of development and consolidation of each track.5. In NWDI version as of 7.00 SP 13 all CBS Buildspaces are updated automatically during save in the NWDI CMS Landscape Domain Data UI. Nevertheless you need to resave all tracks that have a development and / or consolidation runtime system defined to update the user / password for the auto deployment functionality:a) For each track having development and / or consolidation runtime system defined switch to change mode in Landscape Configurator and save the track without any change.6. If you have stopped CBS in the first step, restart CBS on all CBS servers.7. Update User/Password Configuration of name server in the configured DTR Servers

Check the name server configuration of your DTR server as described in the following SAP Help documentation (see section “Configuration of the Name Service”): http://help.sap.com/saphelp_nw04/helpdata/en/b9/b4de3f68d48f15e10000000a155106/content.htm
If the user/password in the name server configuration is not updated with the new NWDI admin user/password configuration you have to set the new user/password manually.
